5w20 Royal Purple in 107 ci?

[Blade]

My friend just put 5w20 Royal Purple synthetic in his 2003 Big Dog Chopper. He tells me that someone told him that the thinner oil would be just fine. Can I get a few more opinons from you guy's so I can tell him before he messes up his bike?

too light for hot weather slow traffic. great if you live in alaska.

better tell him to go back to 20/50

Not good...

5/20 in Florida on an aircooled motor!

Always use the manufacturers recomended oil viscosity. If he is having problems he needs to identify the cause. 5W20 is too light.

Just go to Wal Mart (motorcycle section) & purchase Mobil One~V-Twin~Full Synthetic~20W-50 It is recomended by S&S. $8.99 a quart

Might as well run water in it, or fill it with WD/40!!!

 

[HOOLIGAN]

way too light, especially in the Florida heat!!

I wouldn't run that. PR makes 20W50.

His friend that told him that probably works at the Harley dealership and needs to increase sales this month or get fired! Hell, go ahead and tell him to run it in there for a while and give us some feedback on it!

Don't say that, someone will try to clean their motor out with it:roll::roll::roll:

Royal Purple uses Molybdenum Disulfide (Moly and I'm not a fan of this "" remember slick 50"? I won't get into the oil wars as this has been discussed before but hears.. a good link ..Fluids!! - BIG DOG Motorcycle Forums

When it comes to oil everyone has favorites just do a bit of searching ..its amazing how a bit slick advertising can cloud a otherwise smart decision. Me I would never put anything with Moly in a air cooled motor .
